- ItemAdiponectin levels, cardiometabolic risk factors and markers of subclinical atherosclerosis in children(ELSEVIER IRELAND LTD, 2010) Arnaiz, Pilar; Acevedo, Monica; Barja, Salesa; Aglony, Marlene; Guzman, Beatriz; Cassis, Berta; Carvajal, Jacqueline; Moreno, Manuel; Navarrete, Carlos; Berrios, XimenaBackground: Low levels of adiponectin have been associated with metabolic risk factors (RF) and cardiac disease. Minimal data is available about the relationship between adiponectin and subclinical atherosclerosis. Objectives: To determine the relationship of adiponectin to cardiometabolic RF, C-reactive protein (CRP), anthropometric parameters of obesity, and subclinical atherosclerosis in children.
- ItemCardiovascular risk factors among young subjects with high carotid intima media thickness(SOC MEDICA SANTIAGO, 2011) Acevedo, Monica; Kraemer, Veronica; Tagle, Rodrigo; Arnaiz, Pilar; Corbalan, Ramon; Berrios, Ximena; Navarrete, CarlosBackground: Cardiovascular risk factor (RF) assessment is essential to prevent and predict cardiovascular disease. The presence of RF at early ages, are determinant for the presence of atherosclerosis later in life. Aim: To determine the RF profile of young subjects with high carotid intima media thickness (CIMT). Material and Methods: We studied 689 subjects (50% women, mean age 36 6 years) from Santiago, Chile. We determined body mass index (BMI), waist circumference, blood pressure, fasting serum lipids, blood glucose and C-reactive protein. CIMT was assessed by ultrasound using an automatic border recognition software. Results: Body mass index, waist circumference, blood pressure and serum lipids were significantly higher among subjects located in the higher CIMT quartile. Also, subjects in the higher quartile of CIMT had a higher prevalence of three or more RF compared with the lower quartile (p = 0.01). Finally, individuals with three or more RF showed three times more risk of being in the higher CIMT quartile, than subjects with no RF (odds ratio = 3.1, p < 0.01). Conclusions: There is a negative influence of cardiovascular RF on CIMT among young subjects. (Rev Med Chile 2011; 139: 1322-1329).
- ItemCardiovascular risk factors in a group of health care workers(SOC MEDICA SANTIAGO, 2012) Kramer, Veronica; Adasme, Marcela; Jose Bustamante, M.; Jalil, Jorge; Navarrete, Carlos; Acevedo, MonicaBackground: Health promotion can be carried out at work places. Aim: To assess cardiovascular risk factors among workers of a University hospital. Material and Methods: Cross sectional study of 888 participants (aged 41 +/- 11 years, 76% women), who answered a survey about cardiovascular risk factors. Body mass index, waist, blood pressure and total cholesterol (TC) by capillary method were determined. Results: Self reported prevalence of risk factors were as follows: 19% of participants had high blood pressure, 30% hypercholesterolemia, 6% diabetes, 41% smoked, 88% were sedentary and 26% had a family history of cardiovascular diseases. Five percent of participants did not have any risk factor, 20% had one risk factor, 32% had two and 43% had three or more. The highest frequency of lack of awareness was about blood glucose values. A high blood cholesterol level was found in 27% of those reporting normal cholesterol levels. Likewise, a high body mass index was found in 18% of those reporting a normal weight. Conclusions: The prevalence of cardiovascular risk factors in this group of participants is similar to that found in the last national health survey in Chile. Noteworthy is the lack of awareness about these risk factors. (Rev Med Chile 2012; 140: 602-608).
- ItemCommon Carotid Artery Intima-Media Thickness: The Cardiovascular Risk Factor Multiple Evaluation in Latin America (CARMELA) Study Results(KARGER, 2011) Touboul, Pierre Jean; Vicaut, Eric; Labreuche, Julien; Acevedo, Monica; Torres, Victor; Ramirez Martinez, Jesus; Vinueza, Raul; Silva, Honorio; Champagne, Beatriz; Hernandez Hernandez, Rafael; Wilson, Elinor; Schargrodsky, Herman; CARMELA Study InvestigatorsBackground: Measurement of far wall common carotid artery intima-media thickness (CCAIMT) has emerged as a predictor of incident cardiovascular events. The Cardiovascular Risk Factor Multiple Evaluation in Latin America (CARMELA) study was the first large-scale population-based assessment of both CCAIMT and cardiovascular risk factor prevalence in 7 Latin American cities; the relationship between CCAIMT and cardiovascular risk markers was assessed in these urban Latin American centers. Methods: CARMELA was a cross-sectional, population-based, observational study using stratified, multistage sampling. The participants completed a questionnaire, were evaluated in a clinical visit and underwent carotid ultrasonography. Clinical measurements were obtained by health personnel trained, certified and supervised by CARMELA investigators. Mannheim intima-media thickness consensus guidelines were followed for measurement of CCAIMT. Results: In all cities and for both sexes, CCAIMT increased with higher age. CCAIMT was greater in the presence of cardiovascular risk factors than in their absence. In all cities, there was a statistically significant linear trend between increasing CCAIMT and a growing number of cardiovascular risk factors (p < 0.001). After adjustment for age and sex, metabolic syndrome was strongly associated with increased CCAIMT (p < 0.001 in all cities), as were hypercholesterolemia, obesity and diabetes (p < 0.001 in most cities). By multivariate analysis, hypertension was independently associated with an increase in CCAIMT in all cities (p < 0.01). Conclusions: CARMELA was the first large-scale population study to provide normal CCAIMT values according to age and sex in urban Latin American populations and to show CCAIMT increases in the presence of cardiovascular risk factors and metabolic syndrome.

- ItemComparison of Lipoprotein-Associated Phospholipase A2 and High Sensitive C-Reactive Protein as Determinants of Metabolic Syndrome in Subjects without Coronary Heart Disease: In Search of the Best Predictor(HINDAWI LTD, 2015) Acevedo, Monica; Varleta, Paola; Kramer, Veronica; Valentino, Giovanna; Quiroga, Teresa; Prieto, Carolina; Parada, Jacqueline; Adasme, Marcela; Briones, Luisa; Navarrete, CarlosHigh sensitivity C-reactive protein (hsCRP) is a marker of metabolic syndrome (MS) and cardiovascular (CV) disease. Lipoproteinassociated phospholipase A2 (Lp-PLA2) also predicts CV disease. There are no reports comparing these markers as predictors of MS. Methods. Cross-sectional study comparing Lp-PLA2 and hsCRP as predictors of MS in asymptomatic subjects was carried out; 152 subjects without known atherosclerosis participated. Data were collected on demographics, cardiovascular risk factors, anthropometric and biochemical measurements, and hsCRP and Lp-PLA2 activity levels. A logistic regression analysis was performed with each biomarker and receiver operating characteristic (ROC) curves were constructed for MS. Results. Mean age was 46 +/- 11 years, and 38% of the subjects had MS. Mean Lp-PLA2 activity was 185 +/- 48 nmol/mL/min, and mean hsCRP was 2.1 +/- 2.2mg/L. Subjects with MS had significantly higher levels of Lp-PLA2 (P = 0.03) and hsCRP (P < 0.0001) than those without MS. ROC curves showed that both markers predictedMS. Conclusion. Lp-PLA2 and hsCRP are elevated in subjects withMS. Both biomarkers were independent and significant predictors for MS, emphasizing the role of inflammation in MS. Further research is necessary to determine if inflammation predicts a higher risk for CV events in MS subjects.

- ItemHipertensión arterial: el factor de riesgo más importante para grosor íntima-media carotídeo elevado y placa carotídea en adultos de Santiago(SOC MEDICA SANTIAGO, 2011) Acevedo, Monica; Tagle, Rodrigo; Kramer, Veronica; Arnaiz, Pilar; Marin, Arnaldo; Pino, Felipe; Godoy, Ivan; Berrios, Ximena; Navarrete, CarlosBackground: Carotid Ultima media thickness (CIMT) is a marker of cardiovascular damage that can be modified by traditional risk factors. Aim: To determine attributable risk factors for a high CIMT among healthy adults. Material and Methods: A sample of 1270 individuals (636 males and 634 females) aged 44 +/- 11 years, was studied. Blood pressure, weight, height, lipid profile and blood glucose were measured in all. CIMT and the presence of atherosclerotic plaques were determined by carotid ultrasound. Standard criteria were used to define hypertension, dyslipidemia and diabetes. Results: Mean CIMT in the sample studied was 0.62 +/- 0.01 mm and percentile 75 was 0.67. The most important risk factor for a CIMT over percentile 75 and the presence of atherosclerotic plaques was hypertension with attributable risks of 54 and 57%, respectively. Conclusions: In this sample, the main risk factor for a high CIMT was hypertension. (Rev Med Chile 2011; 139: 290-297).
- ItemTotal/HDL cholesterol ratio and non HDL cholesterol as predictors for increased intima media thickness(SOC MEDICA SANTIAGO, 2012) Acevedo, Monica; Kraemer, Veronica; Tagle, Rodrigo; Corbalan, Ramon; Arnaiz, Pilar; Berrios, Ximena; Navarrete, CarlosBackground: LDL, HDL cholesterol and triglycerides, are the most commonly used lipid cardiovascular risk predictor indicators. However population based studies have shown that non-HDL cholesterol and total/HDL cholesterol ratio are better predictors, are easy to measure and do not require fasting. Aim: To determine which lipid indicators are better determinants of subclinical atherosclerosis, measured by intima media thickness (IMT) among subjects without demonstrated atherosclerosis. Material and Methods: Lipid profile, height, weight, blood pressure and bilateral IMT measured by ultrasound with automatic border recognition software, were assessed in 770 men and 854 women aged 45 +/- 11 years, in Santiago de Chile. Results: Mean total cholesterol was 202, HDL 50, LDL 121, triglycerides 157 and non-HDL cholesterol 152 mg/dl. Total/HDL cholesterol ratio was 4.3. Mean IMT was 0.62 mm. All lipid markers were significantly correlated with IMT This correlation was higher for non-HDL cholesterol (r = 0.24, p < 0.0001) and total/HDL cholesterol ratio(r = 0.23, p < 0.0001). In both men and women, total/HDL cholesterol ratio was the best predictor of having an IMT over the 75th percentile (odds ratio 1.21, 95% confidence intervals 1.09-1.35, p < 0.01). Conclusions: Total/HDL cholesterol ratio was the best determinant of subclinical atherosclerosis. (Rev Med Chile 2012; 140: 969-976).
